How to make a copper touch strip for a clock with ESP32?

Hi, listening I am starting my fun with electronics. My first project is a clock along with a thermometer, barometer and hygrometer. The whole thing will be based on ESP32. A visualization is attached. Wood construction and now I have a question. On the left side I would like to make a copper strip that when touched would light up the LED display. I did something like this on a touch sensor ( Link ). Nevertheless, I don't know what to use to make this copper strip act as such a touch sensor? Should I use an operational amplifier, a transistor? Can you suggest how to do this?

.

Look at the TTP223 chip.

ESP32 already has a special mode for some of the pins that can work as a so called touch pad, so apart from "mechanics" basically nothing else is needed. Here you have examples of how such inputs are handled:

The whole fun mainly comes down to software calibration of such a sensor.
